> Currently, statistics are not updated for minor compaction since minor 
> compaction performs little updates on the statistics (such as number of files 
> in table/partition & total size of the table/partition). It is better to 
> utilize NOSCAN operation  for minor compaction since NOSCAN operations 
> performs faster update of statistics and updates the relevant fields such as 
> number of files & total sizes of the table/partitions.
